While much of the nation is cooling down, it has been an exceptionally hot start to fall in the Bay Area and a California. And the warm weather is here to stay for the time being.

The combination of soaring thermomeaters and bad air forced the Bay Area Quality Management District to issue a rare weekend Spare the Air alert. Monday and Tuesday were expected to follow suit.

San Francisco was predicted to have a high of 84 over the weekend, while the inland valleys were expected to push 100 degrees.

But the Bay Area is not alone in feeling the heat. After what was considered a cooler than usual summer in Southern California that kept many people from the beach, downtown Los Angeles was scheduled to break a 47-year-old record temperture with a high of 107 degrees Monday. Sunday was 105, sending scores of people back to the coast. .
